The flange warping is not a concern. The reason the large holes are in the flange between the ports is to let the heat from the head dissipate as well as the heat from the flange dissipate faster. In addition, the flanges are more than thick enough at 3/8" thick. We also have them made out of mild steel opposed to stainless steel. Stainless steel flanges have a higher probability of warping with excessive amounts of heat applied to them. When our headers are released, all of the flanges will be mild steel and then nickel plated. The reason we nickel plate them is to ensure that they never rust. The nickel plating will hold up to the heat just fine on a N/A or supercharged application. If you want the headers ceramic coated then the nickel plating does not apply...
